Karosa (Czech: Továrna na Kočáry, Automobily, Rotory, Obráběcí stroje, Sekací stroje a Autobusy, English: Factory for carriages, cars, rotors, machine tools, cutting machines and buses) was a bus manufacturer in Vysoké Mýto in the Czech Republic.

In the 1930s, Sodomka became a successful company, winning automotive competitions for elegance and opening showrooms.

At the end of the 1950s, Karosa began to produce the first well-known, popular models of urban buses such as the 706 RTO (for this model, however, Karosa only built the body), which were exhibited at numerous international exhibitions (e.g. Expo 58 in Brussels in the year 1958).

In 1989, after the fall of the communist regime, Karosa had to adapt to the massive socio-economic changes, and its buses became conceptually underdeveloped.

In 1999, Karosa became part of a pan-European venture holding company, Irisbus, which was founded by Renault and its Italian partner, Iveco.

Buses made in Karosa's Vysoké Mýto plant were sold in France, Italy, Germany, Finland, Switzerland, the Benelux countries, the Russian Federation and even in countries such as Guadeloupe in the Caribbean, Réunion Island in the Indian Ocean, Beirut and in Egypt.
